T all whom t 'may concern.'

Be it known that Josnrn: D. MARTIN, a subject of the King of England, residing at Summerside, in the Province of Frince Edward Island and Dominion of Canada, have invented certain new and useful improvements in a Rail-Securing levice, of which the following is a specilication.

The present invention relates to a rail securing device, and aims to provide a novel and improved device of this character which can be conveniently and efiiciently attached to a rail for securely holding the saine in a fixed position against lateral or creeping movement upon a crosstie.

Another object is the provision of a base plate secured to a substantially Eel-shaped metallic crosstie, said base plate especially designed for supporting a rail and being constructed with upwardly projecting portions for engaging the base Flange of the rail to prevent lateral movement thereof, and said plate having arranged thereon at each side thereof a detachable cleat that overlies the base flange of the rail to hold the same to the base plate and tie.

A furt-her object of the invention is to provide a U-shaped crosstie having the side walls thereof converging as they extend upwardly, and a base plate positioned on the upper edges of said converging side walls, said base plate having diverging end portions thereon for engaging the outer sides of the side walls of said crosstie, said base plate also having downwardly extending lugs thereon forengaging the inner upper edges of the converging side walls of the U-shaped crosstie.

A still further object of the invention is to provide a silencer plate constructed of hard rubber, or the like, adapted to be positioned between the rail and the base plate to eliminate noise when rolling stock passes thereov r, said silencer plate being also arranged at this point to eliminate the tendency of the rail cr eping on the base plate, which often occursI with the present type of construction.

lt is also an object of the invention to provide a rail securing device of the kind indicated, which is simple and substantial in construction, which can be manufactured economically, and which will be thoroughly efficient and practical in use.

lVith the foregoing and other objects in view, which. will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts, as hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a perspective view of my improved device showing the same attached to a rail,

Figure 2 is a vertical cross section therethrough,

Figure 3 is a section taken on line 3-3 of Figure 1, and

Figure 4 is a section on line f1-4 of Figure 2.

In carrying out the invention, there is provided a U-shaped metallic crosstie having a base portion 11 and upstanding side portions 12, said side portions being designed to converge towards each other as they extend upwardly. Positioned adjacent each end of the crosstie 10 is a plate 13 having its opposite ends 14 extending downwardly and diverging from each other so as to engage the outer sides of the side walls 12 of the U-shaped crosstie 10. The diverging ends of the plate 13 and the upper edges of the converging side walls 12 are provided with aligned openings through which bolts 15 extend for rigidly securing the plate 13 in a fixed position on the crosstie 10. @n the underside of the plate 13 and adjacent each end thereof are formed downwardly projecting flanges 16 extending the entire width of said plate for engaging the inner upper edges of said side walls 12 to aid in supporting the plate 13 against displacement on the tie. By constructing the U-shaped crosstie as shown in Figure 1 of the drawings, it will be noted that the converging side walls 12 when engaged by the base plate 13 will form a rigid structure which will not be distorted or give way Iwhen rolling stock of the maximum weight passes thereover.

Extending above and across the tie 10 is a rail 17the base thereof engaging a silencer plate 18 of hard rubber, or the like, which is positioned between the same and the upper face of the base plate 13. Arranged upon the lower surface of the silencer plate 18 are provided downwardly extending lugs 1.9 integral therewith, for engaging in openings 2O formed in the base l ll plate 13, such structure preventing said silencer plate from spreading or creeping on the base plate when rolling stock passes over the rail. The silencer plate 18 will also eliminate to a great extent a metallic sound by the engagement of the rail With the base plate should the same not be provided.

On each side and adjacent each end oi the plate 13 upwardly extending ribs 21 integral with said plate are arranged to engage the sides of the base flange of the rail 17 to hold the same against spreading r lateral movement on said plate. To prevent the rail from leaving the base plate 13 a cleat 22 is provided on each side 01"' the rail and is attached to an outwardly projecting portion 23 formed on each side and intermediate the ends of the base plate, said plate being secured to said outwardly extending portions by bolts 2. The cleats overlap the base tiange of the rail and have shoulders thereon tor engaging the edges of said rail base tlange and the side er ges of the silencer plate 18 to hold said rail and silencer plate in proper position on said base plate. A

After the device has been completely assembled, it will be apparent that the base plate is held against lateral movement on the ll-shaped crosstie by the diverging end portions 1st and the lianges 16 engaging said til-shaped crosstie, while sliding or longitudinal movement of the base plate is prevented by the bolts 15, and that the rail 17 is engaged by the ilanges 2l and cleats 22 to hold said rail against spreading or lateral movement on the base plate, while the silencer plate 18 will eliminate to a great extent any creeping or longitudinal movement ot the rail on tho base plate lshould the tendency ot such moifement oeciir 'with the use ot' my improved. device.

Having thus descrilied my invention, what is claimed as new is:

1. A dei/*ice ot the character described, comprising a substantially tl-shaped crossiie, the side walls of' said U-shaped crosstie converging they extend upwardly, a base plate arranged upon the upper edges ot the side walls ot said ifi-shaped crosstie, said base plate having its opposite ends diverging from each other as they extend downwardly for engaging the outer sides of said converging side walls oi' said U-shaped crosstie, means for securing said diverging ends of said base plate to said converging side walls of said crosstie, and a rail carried by said base plate.

2. A device of the character described, comprising a substantially U-shaped crosstie, the side walls of said iii-shaped crosstie converging as they extend upwardly, a base plate arranged Upon the upper edges of the side walls of said U-shaped crosstie, said base plate having its opposite ends diverging from each other as they extend downwardly for engaging the outer sides of said converging side walls of said U-shaped crosstie, means for securing said diverging ends of said base plate to said converging side walls ot said crosstie, downwardly eX- ding flanges carried by said base plate ior engaging the inner sides of said converging side walls of said U-shaped crosstie, and a rail carried by said base plate.

2?. device of trie character described, comprising a substantially tl-shaped crosstie, a base plate arranged upon the opposite side walls of said U-shaped crosstie, said base plate having its opposite ends bent downwardly for engaging the outer sides ot said side walls ot said crosstie, means 'for securing said bent down portions ot' said base plate to said. side Walls, downwardly extending flanges carried by said base plate 'for engaging the inner sides ot' the side walls of said crosstie, a second plate positioned upon said base plate, a rail positioned upon said second mentioned plate and adapted to be siipported. by said hase plate, up "ardly extending flanges cai'- ried by the `nase plate at the opposite sides thereof ior engagin the base iiange of said rail and the side coges of said second. inentioned }j late, outwardly extending portions formed on the opposite sides o1E said base plate, cleats attached to said extension portions of said base plate and adapted to overlap the base fiange of said rail, and a shoulder formed on each oit said cleats for engaging the edge ot the base flange of said rail and the edge ot said second mentioned plate.

In testimony whereof, I have affixed my signature.

JOSEPH D. MARTIN.
